In some embodiments, a computer system may buffer, in a local storage buffer, data to be stored at the cloud and upload the data to the cloud storage from the local storage buffer. Upon receipt of an acknowledgement, from the cloud storage, that the data was successfully uploaded, the computer system may delete the data from the local storage buffer. The computer system may provide a ghost file representation of the uploaded data through the computer system, through which the data uploaded to the cloud storage may be accessed. In some embodiments, the computer system may access multiple cloud storage accounts, each corresponding to a file folder on the computer system, allowing the user to easily access different cloud storage accounts. The computer system may recover data that was deleted from either local persistent storage or the cloud storage.

Embodiments for a method performing data migration such as backups and restores in a network by identifying characteristics of data in a data saveset to separate the data into defined types based on respective characteristics, assigning a data label to each defined type by receiving user selection or automatically merging or selecting a priority label, from among many labels associated with a file, defining migration rules for each data label, discovering assigned labels during a migration operation; and applying respective migration rules to labeled data in the data saveset. The migration rules can dictate storage location, access rights, replication periods, retention periods, and similar parameters.

A method of migrating a network file copy (NFC) operation from a first host computing device to a second host computing device includes the steps of: transmitting a first request to the first host computing device to execute the NFC operation, wherein the NFC operation comprises transferring data from a shared datastore to another datastore; after transmitting the first request, selecting the second host computing device to complete the NFC operation in place of the first host computing device, and transmitting a second request to the first host computing device to stop executing the NFC operation; after transmitting the second request, detecting a message indicating that the first host computing device completed the copying of a first portion of the data; and in response to the detection of the message, transmitting a third request to the second host computing device to perform the remainder of the NFC operation.

Systems and methods are disclosed for cross-system storage management for transferring data across autonomous information management systems. Data may be transferred from one information management system to another information management system without interfering with or overriding each system's autonomy. For example, a secondary copy of production data (e.g., backed up data) is transferred from a first information management system that originated the data to a component of another “foreign” information management system. A first storage manager that manages the first information management system also manages the cross-system data transfer operation to a “foreign” client computing device, which remains under autonomous management as a component of the foreign information management system.

A method, non-transitory computer readable medium, and device that replicates data and provides instantaneous access to data includes receiving in a destination volume one or more named data extents and one or more references to the one or more named data extents associated with a file in parallel from a source volume. A determination is made to check whether the one or more references arrive before the one or more named data extents arrive. Each of the received one or more references which are determined to have arrived prior to the one or more data extents is allocated as absent by the storage management computing device. An instantaneous access to the file is provided during the allocation.

A method of migrating a network file copy (NFC) operation from a first host computing device to a second host computing device includes the steps of: transmitting a first request to the first host computing device to execute the NFC operation, wherein the NFC operation comprises transferring data from a shared datastore to another datastore; after transmitting the first request, selecting the second host computing device to complete the NFC operation in place of the first host computing device, and transmitting a second request to the first host computing device to stop executing the NFC operation; after transmitting the second request, detecting a message indicating that the first host computing device completed the copying of a first portion of the data; and in response to the detection of the message, transmitting a third request to the second host computing device to perform the remainder of the NFC operation.

A computerized-method to conduct a staggered maintenance activity based on tenants' prioritization for tenants of a cloud-based Software as a Service (SaaS) platform contact-center, is provided herein. The computerized-method includes operating a Staggered-Maintenance-Activity (SMA) module. The SMA module includes: (i) selecting a plurality of tenants from the data store of one or more tenants, for a migration activity; (ii) allocating each tenant in the plurality of tenants for migration activity, to a maintenance-window of one or more maintenance-windows; (iii) prioritizing the allocated plurality of tenants to yield an ordered list of tenants, in each maintenance-window of the one or more maintenance-windows; (iv) operating a migration activity during each maintenance-window, of the one or more maintenance-windows, according to the yielded ordered list of tenants; and (v) sending a notification with details of each migration activity to a corresponding tenant administrator, to be displayed, via a display unit.

Embodiments for providing cache updates in a hierarchical multi-node system, through a service component between a lower level component and a next higher level component by maintaining a ledger storing an incrementing entry number indicating a present state of the datasets in a cache of the lower level component. The service component receives a data request to the lower level component from the higher level component including an appended last entry number accessed by the higher level component, and determines if the appended last entry number matches a current entry number in the ledger for any requested dataset, wherein no match indicates that at least some data in the higher level component cache is stale. In which case, it sends updated data information for the stale data to the higher level component, while the higher level component invalidates its cache entries and updates the appended last entry number to match a current entry number in the ledger.

Methods and systems for transferring a host image of a first machine to a second machine, such as during disaster recovery or migration, are disclosed. In one example, a first profile of a first machine of a first type is compared to a second profile of a second machine of a second type different from the first type, to which the host image is to be transferred. The first and second profiles each comprise at least one property of the first type of first machine and the second type of second machine, respectively. At least one property of a host image of the first machine is conformed to at least one corresponding property of the second machine. The conformed host image is provided to the second machine, via a network. The second machine is configured with at least one conformed property of the host image.

A backup method is provided for a file system for managing hierarchical storage including one or more storage media on a computer system including one or more computers. Each of the one or more storage media includes a data part which is separated from an index and on which updated information is appended and kept. Each of a plurality of pieces of data within the file system is managed to be migrated to at least any of the one or more storage media. The backup method includes backing up metadata of the plurality of pieces of data migrated within the file system; and backing up the index of each of the one or more storage media to which the plurality of pieces of data have been migrated, substantially at the same time point as the metadata.
